Using The Integrated Management Module - IBM x3690 X5 Service Manual

Using the integrated management module

The integrated management module (IMM) is a second generation of the functions
that were formerly provided by the baseboard management controller hardware. It
combines service processor functions, video controller, and remote presence
function in a single chip.
The IMM supports the following basic system management features:
v Active Energy Manager.
v Alerts (in-band and out-of-band alerting, PET traps - IPMI style, SNMP, e-mail).
v Auto Boot Failure Recovery (ABR).
v Automatic microprocessor disable on failure and restart in a two-microprocessor
v Automatic Server Restart (ASR) when POST is not complete or the operating
v A virtual media key, which enables remote presence support (remote video,
v Boot sequence manipulation.
v Command-line interface.
v Configuration save and restore.
v DIMM error assistance. The Unified Extensible Firmware Interface (UEFI)
v Environmental monitor with fan speed control for temperature, voltages, fan
v Intelligent Platform Management Interface (IPMI) Specification V2.0 and
v Invalid system configuration (CNFG) LED support.
v Light path diagnostics LEDs indicators to report errors that occur with fans,
v Nonmaskable interrupt (NMI) detection and reporting.
v Operating-system failure blue screen capture.
v PCI configuration data.
v PECI 2 support.
v Power/reset control (power-on, hard and soft shutdown, hard and soft reset,
v Query power-supply input power.
v ROM-based IMM firmware flash updates.
v Serial over LAN (SOL).
v Serial port redirection over telnet or ssh.
v SMI handling.
v System event log (SEL).
The IMM also provides the following remote server management capabilities
through the OSA SMBridge management utility program:

system hangs and the operating system watchdog timer times-out. The IMM
might be configured to watch for the operating system watchdog timer and
reboot the system after a timeout, if the ASR feature is enabled. Otherwise, the
IMM allows the administrator to generate a nonmaskable interrupt (NMI) by
pressing an NMI button on the light path diagnostics panel for an
operating-system memory dump. ASR is supported by IPMI.
